Will a Stock 489 handle 700hp?

Yeah, I'm more concerned with 8 3/4 housing integrity than the drop-out itself.. I've seem many more bent housings than damaged drop-outs.
Back in the day, a buddy of mine had to take a torch to his housing, in order to save his Strange axles and spool. Bent so bad, it wouldn't come apart.
Big torque, lots of gear, heavy car, wheel stands.
Yeah, I was going to run a 8.75 But future plans of t-brake made me buy a Dana.
I do wonder though if guys are welding the back brace on without any sort of help to keep it from warping, I'd use a jig to tie the housing studs and ends together maybe along with the mittler narrowing jig. Just a thought.
